Title: Mold clamping device
Inventor: SHIMA YOSHIHARU
IPC: B29C45/67
Filed: 1988-09-15
Granted: 1991-11-19
Abstract: ABSTRACT OF THE INVENTION       A front oil chamber and a rear oil chamber for oil pressure of a clamping cylinder is connected each other by a connecting path provided in a piston section of a clamping ram, when the piston section moves for mold opening or mold closure, the oil travels between the front and rear chambers via the connecting path to prevent generating negative pressure in the clamping cylinder.      At that time, oil is introduced into or discharged from the clamping cylinder from or to a charge tank, too, via a second open-close valve.  During mold clamping after mold closure, the second open-close valve is closed to move a first open-close valve to close the connecting path of the piston section of the clamping ram for tight clamping.      At that time, the front oil chamber of the clamping cylinder is kept at low pressure by a relief valve,  During mold opening, the oil is supplied to an oil chamber for valve opening from an oil chamber for mold opening via a through-hole bored in the clamping ram to open the connecting path of the piston section of the clamping ram. In the present invention,  the front oil chamber of the clamping cylinder and the charge tank are kept at low Pressure throughout cycle, they need not be a pressure proof structure.      And the oil circuit for operating the first open-close valve can be simple.

Patent CA-1337152-C (CA)
Inventor: STUBBING THOMAS JOHN
IPC: D06F58/48
Filed: 1988-11-10
Granted: 1995-10-03
Abstract: The invention provides a method and apparatus for energy efficient drying of moist material,  for example washed garments,  using superheated steam as the drying medium.  Apparatus for carrying out the method comprises a casing which is thermally insulated and gas-tight apart from an outlet vent.  The air initially within the casing is circulated by a fan through a heat source and through moist garments.   The heated air produces steam from the moisture  in  the garments which,  due  to  the  resultant increase in pressure in the casing, eventually displaces the air from the casing.  Continued recirculation of the steam  through  the  heat  source  causes  it  to  become superheated.  As the process continues, and more moisture is  evaporated  from  the  garments,  a  portion  of  the superheated steam is continually discharged through the vent, where it passes into a condenser where its thermal energy is recovered and is transferred by heat exchange to, for example, water which may be used for other purposes.

Title: Method and apparatus for winding a web
Inventor: SNYGG KEIJO
IPC: B65H19/30
Filed: 1989-06-30
Granted: 1995-08-22
Abstract: The invention relates to a method for on-machine winding of a web,  in which method a Pope-type reel drum (10) or the like is used,  over which the web  (W)  to be wound is  guided.  In the method new reel spools  (11) are brought into contact with the reel drum (10), after which the web (W) is guided from the fully wound roll to be wound onto a new reel spool (11). In the method primary forks  (14),  when in their upper position,  pick up an empty  reel  spool  (11A,11B)  without  any  auxiliary  equipment. Guided by the primary forks (14) and supported on support plates (17)  attached on primary forks  (14),  the empty,  preaccelerated reel  spool  (11B,11C)  is  brought  into  nip  contact with  the rotating reel drum (10), through the nip of which the web (W) to be wound runs, and is wound about the reel spool (11) at the nip contact. The support plates (17) remain in such a position while the  primary  forks  (14)  are  being lowered that  the  contact pressure between the reel spool (11C-11E) and the reel drum (10) remains essentially constant as the primary forks (14) move from the upper position to the lower . When the primary forks (14) are in the  lower position,  the  support  plates  turn into  such  a position that they pass the reel spool  (11),  which is already positioned on the reel tracks (12), when the primary forks (14) are moving back into their upper position,  and the above steps are repeated when it is time to exchange reel spools again and the support plates are ready to receive one.  The invention also relates to the apparatus used in the method.
